The application of the essential work of fracture (EWF) methodology for the fracture
behavior characterization of closed-cell low density polyethylene flexible foams is discussed in the
present paper. The thickness of the foamed sheet and the relative orientation of the initial crack were
the main parameters studied. The interpretation of the results is carried out on the basis of the material
microstructure and the applicability of the testing method.
